Great Product and Straight Forward Installation
High Quality Product. Installed on 2001 Chevy Tahoe with 5.3L V8. Installation is straight forward. Installation did require minor bend modification to the heat shield on the passenger side, so it didn't touch the Header Tube. Doug Thorley Header performs well and am very pleased with their product. Highly recommend this product.
